This guide will show how to install the Arduino-ESP32 support.

Before Installing
-----------------

We recommend you install the support using the Boards Manager, but other options are available depending on your operating system. 
To install Arduino-ESP32 support, you can use one of the following options.

Installing using Boards Manager
-------------------------------

This is the preferred and easiest way to install Arduino-ESP32.

.. note::
   Currently, the support for new chips (ESP32-S2 and ESP32-C3) is in the development release. Consider installing the development release if you need to test the new supported SoC in beta.

- Stable release link::

- Development release link::

   https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_dev_index.json


.. note::
   Starting with the Arduino IDE version 1.6.4, Arduino allows installation of third-party platform 
   packages using Boards Manager. We have packages available for Windows, macOS, and Linux.

To start the installation process using the Boards Managaer, follow these steps:

-  Install the current upstream Arduino IDE at the 1.8 level or later. The current version is at the `arduino.cc`_ website.

-  Start Arduino and open the Preferences window.

Windows
-------

Steps to install Arduino ESP32 support on Windows:

**Step 1**

1. Download and install the latest Arduino IDE ``Windows Installer`` from [arduino.cc](https://www.arduino.cc/en/Main/Software)
2. Download and install Git from [git-scm.com](https://git-scm.com/download/win)
3. Start ``Git GUI`` and do the following steps:

- Select ``Clone Existing Repository``

.. figure:: _static/win-gui-1.png

   :width: 600
   :figclass: align-center

- Select source and destination
   - Sketchbook Directory: Usually ``C:/Users/[YOUR_USER_NAME]/Documents/Arduino`` and is listed underneath the "Sketchbook location" in Arduino preferences.
   - Source Location: ``https://github.com/espressif/arduino-esp32.git``
   - Target Directory: ``[ARDUINO_SKETCHBOOK_DIR]/hardware/espressif/esp32``
   - Click ``Clone`` to start cloning the repository

**Step 2**

**Step 3**

.. figure:: _static/win-gui-3.png
   :align: center
   :figclass: align-center

- open a `Git Bash` session pointing to ``[ARDUINO_SKETCHBOOK_DIR]/hardware/espressif/esp32`` and execute ```git submodule update --init --recursive``` 
- Open ``[ARDUINO_SKETCHBOOK_DIR]/hardware/espressif/esp32/tools`` and double-click ``get.exe``

**Step 4**

.. figure:: _static/win-gui-4.png
   :align: center
   :figclass: align-center

- When ```get.exe``` finishes, you should see the following files in the directory

**Step 5**

.. figure:: _static/win-gui-5.png
   :align: center
   :figclass: align-center

1. Plug your ESP32 board and wait for the drivers to install (or install manually any that might be required)
2. Start Arduino IDE
3. Select your board in ``Tools > Board`` menu
4. Select the COM port that the board is attached to
5. Compile and upload (You might need to hold the boot button while uploading)

Linux
-----

Debian/Ubuntu
*************

- Install latest Arduino IDE from `arduino.cc`_.

- Open Terminal and execute the following command (copy -> paste and hit enter):

.. code-block:: bash

   sudo usermod -a -G dialout $USER && \
   sudo apt-get install git && \
   wget https://bootstrap.pypa.io/get-pip.py && \
   sudo python3 get-pip.py && \
   sudo pip3 install pyserial && \
   mkdir -p ~/Arduino/hardware/espressif && \
   cd ~/Arduino/hardware/espressif && \
   git clone https://github.com/espressif/arduino-esp32.git esp32 && \
   cd esp32/tools && \
   python3 get.py

- Restart Arduino IDE.

- If you have Arduino installed to ~/, modify the installation as follows, beginning at `mkdir -p ~/Arduino/hardware`:

.. code-block:: bash

   cd ~/Arduino/hardware
   mkdir -p espressif && \
   cd espressif && \
   git clone https://github.com/espressif/arduino-esp32.git esp32 && \
   cd esp32/tools && \
   python3 get.py

Fedora
******

- Install the latest Arduino IDE from `arduino.cc`_.

.. note::
   Command ``$ sudo dnf -y install arduino`` will most likely install an older release.

- Open Terminal and execute the following command (copy -> paste and hit enter):

.. code-block:: bash

   sudo usermod -a -G dialout $USER && \
   sudo dnf install git python3-pip python3-pyserial && \
   mkdir -p ~/Arduino/hardware/espressif && \
   cd ~/Arduino/hardware/espressif && \
   git clone https://github.com/espressif/arduino-esp32.git esp32 && \
   cd esp32/tools && \
   python get.py

- Restart Arduino IDE.

openSUSE
********

- Install the latest Arduino IDE from `arduino.cc`_.

- Open Terminal and execute the following command (copy -> paste and hit enter):

.. code-block:: bash

   sudo usermod -a -G dialout $USER && \
   if [ `python --version 2>&1 | grep '2.7' | wc -l` = "1" ]; then \
   sudo zypper install git python-pip python-pyserial; \
   else \
   sudo zypper install git python3-pip python3-pyserial; \
   fi && \
   mkdir -p ~/Arduino/hardware/espressif && \
   cd ~/Arduino/hardware/espressif && \
   git clone https://github.com/espressif/arduino-esp32.git esp32 && \
   cd esp32/tools && \
   python get.py

macOS
-----

- Install the latest Arduino IDE from `arduino.cc`_.

- Open Terminal and execute the following command (copy -> paste and hit enter):

.. code-block:: bash

   mkdir -p ~/Documents/Arduino/hardware/espressif && \
   cd ~/Documents/Arduino/hardware/espressif && \
   git clone https://github.com/espressif/arduino-esp32.git esp32 && \
   cd esp32/tools && \
   python get.py 

Where ``~/Documents/Arduino`` represents your sketch book location as per "Arduino" > "Preferences" > "Sketchbook location" (in the IDE once started). Adjust the command above accordingly.

- If you get the error below, install through the command line dev tools with `xcode-select --install` and try the command above again:

.. code-block:: bash

   xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun

- Run the command:

.. code-block:: bash

   xcode-select --install

- Try ``python3`` instead of ``python`` if you get the error: ``IOError: [Errno socket error] [SSL: TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert protocol version (_ssl.c:590)`` when running ``python get.py``

- If you get the following error when running ``python get.py`` urllib.error.URLError: <urlopen error SSL: CERTIFICATE_VERIFY_FAILED, go to Macintosh HD > Applications > Python3.6 folder (or any other python version), and run the following scripts: Install Certificates.command and Update Shell Profile.command

- Restart Arduino IDE.
